ToA all whom z't 'may concern:

Be it known that we, ELBERT B. VAUQHAN and FRED T. KLAsGYE, citizens ofthe United States, and residents of Cleveland, in the county of Cuyahogaand State of Ohio, have invented an -Improvement in Fluid Transmissionfor Motor-Vehicles, of which the following is a specification.

The object of our invention is an improvement in motor .vehicles inwhich a circulating liquid is substituted for gearing for transmittingpower from the motor to thedriving wheels. We have devised anew andadvantageous construction and combination of parts for this purpose, thedetails of which are hereinafter described and illustrated in theaccompanying drawings, 'in which- Figure 1 is a diagrammatic plan viewof the chassis and wheels of an automobile, together' with ourimprovements as applied, thereto. Fig. 2fis a, side view of the same.Fig. 3 is an enlarged vertical section on the line 3 3 of Fig, 2. Fig. 4is a vertical cross section on the line /1-4 of Fig. 3. Fig. 5 is anenlarged horizontal section of a port-ion of our improved apparatus.Fig. 6 is a similar section reduced but showing a different position ofcertain valves. Fig. 7 is a perspective view of the main valveregulating circulation of the motive fluid. Fig. 8 is a cross section onthe line 8-8 of Fig. 1. Fig. 9 is a horizontal sect-ion showing theposition of valves for cutting off circulation through the motors.

Referring lin the first instance to Figs. 1 and 2, the rear wheels 1,la, are mounted on an axle 2 fixed in a chassis 3 and having stubjournals to which the rear running Wheels 1al are applied. Motors 15 and16 are attached to the hubs of said wheels and act independently of eachother but both work alike, both taking the fluid at the under side inforward motion and at the top when reversing. Both motors are used topropel for reversing the vehicle.

At the front of the apparatus there is arranged vertically a motor 7 ofthe turbine type from which pipes 8 and 8a lead rearward, as shown. Thisturbine comprises a cylindrical casing 10-see Figs. 3 and 4rand a rotarydisk 11 keyed upon a horizontal shaft l2 and provided with a series ofradial equidistant pistons 13, which are pressed outward by springs 14and whose outer ends work in\frictional contact with the casing. Thedirection lof rotation is clockwise, or from left to right, as indicatedby arrows in Fig. 3. The shaft 12 o f/this motor pro'ects forward, and,in pract1c e,.1s' 'connecte with a gasolene or other drivlng motor (notshown).

On the rear wheels 1 are arrangedtwo turblnes -15 and 16, which aresimilar in construct-ion to the propelling motor already described. Thepipe 8 leading from the caslng of the prope llng motor extends to, andconnects wlt-h, the lower side of the driving turbines l15 and 16, and areturn pi e 8a leads from said turbines crosswise, as s 'own 70 in Fig.1, and extends back to the propelling motor 7. As shown in Fig. 8, thepipe 8 is connected with the lower `side of the turbines 15 and 16 andthe pipe 8a is similarly connected with theiupper side of the same. Itwill thus be apparent that when the propelling motor 7 is'rotated totheright-see Fig. B -the liquid, say oil, which is contained in the system,will iow along pipe 8 to the lower side of thel motors 15 and 16 and,passing around the same, will return by the pipe 8a to the propellingmotor 7. Thus the vehicle is propelled by turbines 15 and 16. Rotaryvalves 17 and 17a shown in Figs. 5. and 6, are arranged in connectionwith the outflow and return ipes 8, 8, in such manner, that whenad]usted as in Fig. 5, they permitvthe free low of liquid outward andinward; but, when adjusted at the angle shown in Fig. 6, they lcut offthe iow from pipes 8, 8, and direct -the same to and vfrom rear turbines15 and 16. With this position of the valves, it will be seen that theliquid flows from pipe 8 into a cross-pipe 9 and is thus conveyed to theup- \per side ofthe turbines 15 and 16, and that it returns by way ofthe cross-pipe 9 to the pipe 8a and thus back to the propelling turbine7. It will be understood that while, in the case of the propellingturbines l5 and 16, the inflow of liquid is at the bottom and theoutflow lfrom the top, as indicated by arrows in Fig. 8, in the case ofthe reversing turbines 15 and 16, the opposite arrangement is required,the inflow being at the top 105 and the outflow at the bottom.

It is to be understood that we shall employ any suitable means forshifting, that is to say, rotating, the reversing valves 17, 17,

and we do not deem it necessary to describe 110 any particular means forthe purpose, since this is within the skill of the ordinary mechanic.

Between the propelling motor 7 and -the reversing valves 17, 17, thereis arranged, as shown in Figs. 5 and (l, a speed-regulating valve 1S,the same being arranged in a circular chamber 19 which is extendedlaterally into the opposite pipes 8, 8. When the valve is adjusted asshown by full lines in Figs. 5 and 6, that is to say, practicallyparallel to the pipes 8, 8, liquid flows througlrthe pipe 8 and returnsby pipe 8, but when the valve is placed crosswise, as shown in Fig. 8,the circulation of liquid through the pipes 8, 8a, is arrested andmotors l5 and 16 then constitute a brake. Again, it is apparent that thevalve 18 may be adjusted to but partly cut off the flow of liquidthrough the pipes 8, 8a, and by this-means the speed of the vehicle maybe regulated at will, it being greater when the valve is widely openedand correspondingly less when the valve is closed more or less. Vhen theVvalve 18 is set crosswise as in Fig. 9, or the valves 17 and 17a areset as there shown, the circulation of liquid through the motors l5 and1G is arrested and the motors serve as a brake. Such slight waste of themotive liquid as may occur may be resupplied from a tank (not shown)which, in practice, will be connected at Q0 with the pipe S-see Figs. l.and 2.

that we claim is l. The improved liquid power-transmit ting apparatusfor motor vehicles, the same comprising a liquid circulating turbineadapted tor connection with a driving engine. propelling and reversingturbines adapted to be mounted upon a reversible driving axle, outflowand return pipes conacted with the circulating turbine and With therespective propelling and rotary reversin turbines, and reversing valveseach applied at the junction of one of said pipes and a branch from theother, as described.

2. The improved liquid power-transmitting apparatus for motor vehicles,the same comprising a liquid circulating turbine adapted for connectionwith a drivin engine, propelling and reversing tur ines adapted to bemounted upon a reversible driving axle,.outow and return pipes andbranches thereof all connected with the propelling and reversingturbines, rotary reversing valves each applied at the junction of one ofsaid pipes and a branch from the other, and a rotary speed-regulatingvalve arranged between the outflow and inflow pipes and adapted foradjustment practically parallel or at right angles to both said pipes,as described, whereby the flow of liquid to the rear turbine may beentirely or partly cut olf as conditions require.

3. In a motor vehicle, the combination with the rear driving axle, andpropelling and reversing turbines mounted thereon, of a liquidcirculating apparatus comprising a turbine adapted for operation asdescribed, outflow and return pipes and branches thereof connected inpairs with the respective turbines at top and bottom, rotary reversingvalves each applied at the junction of one of said pipes and a branchfrom the other, and a speed-regulating valve arranged in front of thereversing valves and adapted to cut ofi' more or less the outflow andreturn l'low of liquid, as described.
